[Sony Xperia P, U, Sola, Go] perezdi:
Ok, so I flashed the Nordic .54 Stock rom before doing all the procedure, seems like it is all fine, working peachy, except Wi-Fi. I've seen some people reporting it here but I haven't seen nobody coming back with the problem solved.

I'll try now to Wipe Data and Dalvik Cache and reinstall it, I'll come back with the results. If it works, I'll keep it as my rom, if it doesn't, well...

If anyone found already the solution for this problem, please report to the community. Thank you.

EDIT:

Here are my results:

After wiping cache, data, factory reset and reinstalling everything, the same problem with wi-fi was there. It wasn't turning on by any means. It keeps trying to turn on but never gets to it.
